Answer:
16%
Step-by-step explanation:
Find the z-score.
z = (x − μ) / σ
z = (93 − 85) / 8
z = 1
This means 93 is one standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and +1 standard deviations. So 32% is either less than -1 or greater than +1 standard deviations. Normal curves are symmetrical, so 16% is greater than +1 standard deviations.
Answer:
(1,4) IS THE ANSWER. I 100% believe that's the answer
Step-by-step explanation:
I can't explain it. (Next time when you get the same kind of question just look for a clear white paper. Cut it and make sure it's the size as the graph. Then put it on the computer screen then trace the shape that's on the graph and label the points like how they're labeled in your graph. After that, as the paper is one the screen of your computer, place a pencil or a pen on the paper and make sure it's aligned in the center of the graph. Press the pencil or pen a bit hard so the paper won't slide or fall out. After that rotate the paper to the ___degrees that's stated in the question. If the rotation is clockwise go clockwise. If the rotation is counterclockwise go counterclockwise. After that you'll get the answers.)
It’s the third one. Hope that helped!
Answer:
Step-by-step explanation:
There are 10 numbers representing the selling prices of paintings.
<u>List the numbers in the ascending order:</u>
- 50, 200, 250, 280, 350, 375, 400, 400, 410, 1200
<u>Median of the lower half is:</u>
- 50, 200, 250, 280, 350 ⇒ Q1 = 250
<u>Median of the upper half is:</u>
- 375, 400, 400, 410, 1200 ⇒ Q3 = 400
<u>The IQR is the difference between the upper and lower medians:</u>
- IQR = Q3 - Q1 =
- 400 - 250 = 150
